Claims6
An elastic support device for stator winding end turns of a rotating electrical machine comprising a supporting cage which has a central axis, which supports the end turns and which is fixed by means of supports to a clamping plate of said machine, said device comprising elastic fixing means for fixing said supports to said clamping plate, and said elastic fixing means comprising at least one elastic ring to which said supports are fixed and which is fastened to said clamping plate by fastening means;
- said device further comprising a damper screen between said clamping plate and said ring, and means for fixing said damper screen to said clamping plate independently of said ring;
- wherein said clamping plate (2), said elastic ring (3) and said damper screen (10) are disposed in respective planes which are parallel to each other and which are perpendicular to said cage axis and to said supports (8).
An elastic support device for stator winding end turns of a rotating electrical machine comprising a supporting cage which supports the end turns and which is fixed by means of supports to a clamping plate of said machine, said device comprising elastic fixing means for fixing said supports to said clamping plate, and said elastic fixing means comprising at least one ring to which said supports are fixed and which is fastened to said clamping plate by fastening means;
- said device further comprising a damper screen between said clamping plate and said ring, and means for fixing said damper screen to said clamping plate independently of said ring;
- wherein the means for fastening said ring to said clamping plate comprise centering bushing, and wherein said damper screen is separated from said clamping plate by spacers, said device further comprising sealing members disposed between said damper screen and said centering bushings.
